`compileComponents` is not necessary when using the CLI (as the templates are inlined) and just adds boilerplate code. So we can remove it from the test schematic and make it independent from `async/await` (only place we would have it in the CLI generated code, and in most Angular apps).
The CLI usually generates files with a new line at the end.
This line was lacking in the new `app.config.ts` file generated for standalone applications.
It was also using a trailing comma, which is not the usual convention in generated files.
The `imports` are below the `standalone` property when generating a new component with `ng g c`.
This commit moves the `imports` of the standalone `app.component.ts` file to be in a similar place.
